Also, Adam really needs to figure out a a more practical method of inter-dimensional travel that doesn't involve shoving people in his soul. When the Scion issue does get resolved, being able to send Gamers and Questers to those other realities to trade, perform certain tasks or even just travel for EXP and exotic loot would be a boon to many. The cluster of Post-Gold Morning Earths would definitely need some aid, plus all those super villains that are still valid bounty targets for ambitious, aspiring System-empowered parahumans.
Oh, this is true. Transforming himself into sometimes strange beings is hardly reliable way to swap between dimensions. Although in this jump at least he is more or less himself?
Analyzing in more detail Doormaker and Clairvoyant should help? Going back to MLP to find magical way to do so? I think he has options.
Although for example if he would end up in Sigil it would be both a challenge (good luck dealing with Lady of Pain and some top tier characters) and interesting way to learn how to move between dimensions. D&D magic is pretty strong for a good reason.
I am the mind of my body
Queen Administrator is my soul

And as I pray, Unlimited Taylor Escalation!
Unlimited Taylor Escalation?
Oh, this is maybe one of those Trump Taylors that can summon (or directly use as 'templates' on her own body) other versions of Taylors from fanfiction to use their powers and receive their memories

Those are always fun.
He kinda already did, remember he turned his original Worm into an RPG. That's like a step up, to the side and back into being a Rob.
MC is already on a level of low-tier ROB at this point. I don't think we can argue it.
I think at this point a jump to one of those more deadly top-tier universes could be a fun change of pace. I think as I mentioned before he starts to get bored with how easy things go around I feel.
I'm pretty sure Lisa would have an aneurysm when she sees Taylor now.
Perfect control over the body! That means no tells for cold reading, feinting becomes almost perfect in fights. She can also push her body to operate way past her limits! And if she can control whatever is happening inside, she can do self directed healing for her wounds, reduce fatigue buildup, maximize metabolism, and other cool nifty stuff.
Basically, she became the perfect human!
Actually I hope it's not all she has power wise. Like Alexandria Package + Thinker Package (the way I read it) sounds like a pretty simplistic powerset for Taylor, who knows how to be creative and use even weaker advantages to the maximum. So I hope she will get (or simply didn't use yet) her bug control powerset, as it's pretty much her trademark at this point. All she would need is some biokinetic addition and she would be overpowered anyway.
Give her more options/toys to play with

. And don't mutate her too much in the process
